Hi Leedavi!
Thanks for your reply, i've read abode topic. At first, i think about permission for parent folder, but it is OK.

Second, When i upload image for products, it's not save information into database .....example, i uploaded img name 1.jpg, but in database: imageURL is ....../productimages/ ( not save image name ), so my problem is can't upload and save image to database
(and image not upload into productimages folder). And my parent folder name solid.com.vn, i don't think it cause this issue.

Thanks for your reply. I don't receive any error message, but when i move website to another machine ( attach database and create new vitual directory ), it run ok. But i still have another problem, when i clicked on image ( product details ), the Close
button not display, i tried to view its link and see it's ok, but it not effect on my site. I don't understand......

So, i will be try to change solid.com.vn to solidcomvn or another to test. I will reply soon after i do it. Thanks.
